My pressure guage still reads 100 but after 3 days the system now blows hot air. I added 2 cans of refrigerant and it blew good cold air but now there is no sign of cold air? I guess I just did not do something right. Thanks
100 and system was blowing cold air. Now 3 days later after blowing the fan for a short trip home it is blowing hot air but pressure guage still reads 100 and the fitting to the low side port is cold to the touch. What could be wrong here?
